Kungani abanye abantu bedinga izibuko? Izinkinga zokubona nezixazululo (Izibuko nama-Contact Lenses)

Wake wazibuza ukuthi kungani umngane wakho edinga izibuko kuyilapho wena ungazidingi? Noma kungani abanye abantu bedinga izibuko ukuze bafunde incwadi, kuyilapho abanye bedinga izibuko ukuze babone kude? Amehlo ethu akhethekile ngempela, ahlukile komunye nomunye. Ngezinye izikhathi yilapho izingxenye ezincane ngaphakathi kweso zingasebenzi kahle lapho singakwazi ukubona kahle. Kodwa ungakhathazeki, kunezibuko nama -contact lens ukusiza ngalokhu. Ake sixoxe ngalokhu ngokuningiliziwe namuhla, akunjalo?

Amehlo ethu asebenza kanjani? Kuyamangalisa, akunjalo?

Cabanga ngeso lakho njengekhamera encane, eyinkimbinkimbi kakhulu. Ukukhanya yilokho le khamera ekudingayo ukuze idale "isithombe." Kunezingxenye eziningana ezibalulekile ngaphakathi kweso ezisiza ekwenzeni lo msebenzi.

• I-Cornea: Lena yingxenye yeso ecacile, efana newashi. Uma ukukhanya kungena esweni, kuqala kugotshwe, noma kugotshwe, bese kuqondiswa esweni yi-cornea. Ukuze kube sobala, inqubo yokugxila, noma ukugxila, ukukhanya okungena esweni kuqala lapha.
• I-Iris: Ukuthi amehlo akho aluhlaza okwesibhakabhaka, ansundu, ampunga, noma amnyama kuncike kumbala wesikhumba okule "Iris". Lena yingxenye yemisipha.
• Umfundi: Lena yindilinga encane emnyama phakathi kwe-`(Iris)`. Empeleni lena imbobo. Kufana ne-`(aperture)` yekhamera. Uma kunokukhanya okuningi, le `((Umfundi)` iba ncane, futhi uma kunokukhanya okuncane (ebumnyameni), iba nkulu. Umsebenzi wayo oyinhloko ukulawula inani lokukhanya okungena esweni.
• Ilensi: Lena yingxenye esobala ngemuva kwe-`(Umfundi)`, njengengcezu encane yengilazi. Ngemva kwe-`(Cornea)`, i-`(Lensi)` igxila ukukhanya kakhulu futhi ikwenze kuwele ngqo kwi-`(Retina)`. Okukhethekile ngale `(Lensi)` ukuthi ingashintsha isimo sayo (kwenziwa yimisipha emincane) futhi ikusize ubone izinto eziseduze kanye nezinto ezikude ngokucacile.
• I-Retina: Lena ungqimba oluzwela ukukhanya ngemuva kweso. Lufana ne-`(sensor)` ekhamera noma i-`(film roll)` kumakhamera amadala. Lapho ukukhanya okuqoqwe yi-`(Cornea)` kanye ne-`(Lens)` kuwela kule `(Retina)`, kwakheka isithombe lapho. Le `(Retina)` iqukethe izigidi zamaseli akhethekile (`(amaseli e-Photoreceptor)`) azwela ukukhanya nombala. Lawa maseli aguqula ukukhanya kube izimpawu zikagesi.

Ngemuva kwalokho, lezi zimpawu zikagesi zihamba nge -optic nerve ziye ebuchosheni. Ubuchopho buhlaziya lezi zimpawu bese busitshela ukuthi, "Lesi yisithombe osibonayo." Kuyamangalisa okwenzeka ngaphakathi kwaleli so elincane!

Kungani umbono womuntu wonke ungalingani? Yiziphi lezi zinkinga zokubona?

Njengeminwe yethu, amehlo abo bonke ahlukile kancane. Lokho kusho ukuthi izinto ezifana nobude be-eyeball, ukugoba kwe-`(Cornea)`, kanye nesimo se-`(Lens)` kungahluka kumuntu nomuntu. Lokhu kuhluka yingakho abanye abantu bedinga izibuko kanti abanye abadingi. Uma ukukhanya kungagxilile ngqo ku-`(Retina)`, umbono uba lufifi. Sibiza lawa maphutha okubheka emuva . Ake sibheke izinhlobo eziyinhloko zamaphutha okubheka emuva esiwabonayo.

1. I-Myopia noma i-Nearviewing

Yilapho izinto eziseduze nawe zingabonakala khona ngokucacile, kodwa izinto ezikude azicacile. Kufana nokubuka i-TV ukude futhi umbhalo awucacile. Izibonelo zifaka phakathi izingane ezingakwazi ukubona okubhalwe ebhodini elimnyama ekilasini, noma abantu abangakwazi ukufunda uphawu lwebhasi bekude.

• Kungani lokhu kwenzeka? Kalula nje, inhlamvu yeso lakho yinde kakhulu, noma i-"Cornea" noma i-"Lens" yakho inamandla amaningi okugxila. Khona-ke ukukhanya okungena esweni akugxilile ngqo ku-"Retina", kodwa kuphambi kwayo kancane.
• Izibuko zikulungisa kanjani lokhu? Abantu abane-`(Myopia)` banikezwa izibuko ezinamalensi aqondile (amalensi aqondile / amalensi anamandla e-Minus) . Lawa malensi ahlukanisa ukukhanya kancane, okwenza kuwele ngqo ku-`(Retina)`.

2. Ukungaboni Kahle Noma Ukubuka Izinto Ezikude

Kulokhu , nakuba izinto ezikude zingabonakala ngokucacile, izinto eziseduze, ikakhulukazi lapho kufundwa izincwadi, kubhekwe ifoni, noma kuthunga, zibonakala zingacacile. Ngezinye izikhathi, lapho uzama ukubona eduze, amehlo angase akhathale (`(ukucindezeleka kwamehlo)`) futhi kungase kube nekhanda elibuhlungu. Lapho izingane ezincane zine-`(Hyperopia)`, ngezinye izikhathi zingase zibe nesimo lapho amehlo ebheka ngaphakathi (`(amehlo ahlanganisiwe)` / `(Esotropia)`).

• Kungani lokhu kwenzeka? Lokhu kuphambene ne-`(Myopia)`. Kungakhathaliseki ukuthi inhlamvu yeso lakho imfushane kakhulu, noma i-`(Cornea)` noma i-`(Lens)` yakho ayinawo amandla anele okugxila. Bese ukukhanya kuzama ukugxila ngemuva kwe-`(Retina)` (uma sikhuluma iqiniso, i-`(Lens)` kufanele isebenze kanzima ukugxila ngaphezu kwe-`(Retina)`).
• Ukulungisa kanjani lokhu ngezibuko? Abantu abane-`(Hyperopia)` banikezwa izibuko ezinamalensi acwebezelayo (amalensi acwebezelayo / amalensi anamandla e-Plus) . Lawa malensi ahlanganisa ukukhanya ndawonye (ahlanganise) futhi akulethe ku-`(Retina)`.

3. Ukungabi nandaba

Lolu uhlobo oluhlukile kancane lobuthakathaka. Lapha , izinto eziseduze nezikude zingase zibonakale zifiphele, ngezinye izikhathi zeluliwe, futhi zibonakale njengezithunzi. Uma ushayela ebusuku, ungase ubone nokuqhuma kwezinkanyezi eduze kwezibani. I-Astigmatism ingase ibe khona, kanye ne-Myopia noma i-Hyperopia.

• Kungani lokhu kwenzeka?Ngokuvamile, i-`(Cornea)` kanye ne-`(Lens)` yeso eliphilile ziyindilinga, zigobile ngendlela efanayo kuzo zonke izinhlangothi, njengobuso bebhola eliyindilinga. Kodwa-ke, kubantu abane-`(Astigmatism), i-`(Cornea)` (ngokuvamile i-`(Cornea)`) kanye ne-`(Lens)` zimise okweqanda/ibhola, zigobile kakhulu kolunye uhlangothi futhi zigobile kancane kolunye. Bese kuthi, ukukhanya okuvela ohlangothini ngalunye kugxile ngendlela ehlukile, ezindaweni ezahlukene. Yingakho isithombe sibonakala sifiphele futhi sinwebekile.
• Izibuko zikulungisa kanjani lokhu? Zisebenzisa amalensi amise okwesilinda akhiwe ngendlela ekhethekile. Lawa alungisa ukugoba okungalingani futhi agxilise ukukhanya endaweni eyodwa, anikeze umbono ocacile.

4. Ukubona eduze (i-Presbyopia)

Lesi akusona isifo, kodwa ushintsho lwemvelo oluvela ngokuguga. Ngokuvamile luvela kubantu abaningi abaneminyaka engaba ngu-40-45. Ngisho nalabo ababenamehlo amahle ngaphambili bakuthola kunzima ukufunda umbhalo omncane noma ukwenza imisebenzi eseduze, njengokufaka intambo enalitini. Yingakho abantu baleyo minyaka belula izingalo zabo kancane lapho befunda amaphephandaba noma bebheka ocingweni lwabo, futhi ngezinye izikhathi bathi bazizwa sengathi "izandla ziyakhathala."

• Kungani lokhu kwenzeka? Njengoba siguga, i-`(Lens)` engaphakathi kwamehlo ethu ilahlekelwa kancane kancane ukuguquguquka kwayo, okungukuthi, ikhono layo lokushintsha isimo kalula. Uma sisebancane, le `(Lens)` iba yi-convex futhi igxile kalula uma sibheka eduze. Kodwa-ke, njengoba siguga, leli khono liyancipha, ngakho-ke uma sidinga ukubheka eduze, i-`(Lens)` ayikwazi ukugxila kahle.
• Iyini ikhambi? Ungasebenzisa izibuko zokufunda nalokhu, noma amalensi amabili noma amalensi aqhubekayo akuvumela ukuthi ubone kokubili kude naseduze ngezibuko ezifanayo.

Kungani kubaluleke kangaka ukuhlolwa kwamehlo akho?

Uma ubona noma yiziphi izinguquko embonweni wakho – okungukuthi, awukwazi ukubona kahle njengoba wawubona ngaphambili, uphathwa yikhanda elibuhlungu njalo, amehlo akho azizwa ekhathele – noma noma kungekho lutho olungalungile , kubaluleke kakhulu ukuhlolwa kwamehlo okungenani kanye ngonyaka. Njengabazali, kufanele sikhathazeke kakhulu ngombono wezingane zethu. Ngoba bangase bangasho ukuthi abakwazi ukubona. Futhi, abantu abanezifo ezifana ne-`(Diabetes Mellitus)` (Diabetes) bangaba nezinkinga zamehlo, ngakho-ke kubalulekile ukuhlolwa kwamehlo njalo.

Yini evame ukwenziwa ngesikhathi sokuhlolwa kwamehlo?

• Ukuhlolwa Kokubona Okubonakalayo: Yilokhu okufunda eshadini le-Snellen ngeso ngalinye. Kukala ukuthi ubona ngokucacile kangakanani nokuthi ungabona kude kangakanani.
• Ukuhlolwa Kokugqagqama: Lokhu kusetshenziselwa ukuthola ukuthi une-Myopia, i-Hyperopia, noma i-Astigmatism, futhi uma kunjalo, ukuthi yimaphi amalensi anamandla owadingayo. Kungenzeka ukuthi uke wabona umshini obizwa ngokuthi i-Phoropter ohlola ukubona kwakho ngokufaka amalensi ngalinye ngalinye.
• Ukulinganisa umfutho wamehlo (i-Tonometry):Ingcindezi engaphakathi kweso iyalinganiswa. Lokhu kubalulekile ukuze kutholakale isifo esibizwa ngokuthi ``Glaucoma''.
• Ukuhlolwa Kwamehlo Okuvulekile: Ngezinye izikhathi, umfundi uyavuleka ngokusebenzisa amaconsi amehlo, bese izingxenye ezingaphakathi kweso, njenge-retina kanye ne-optic nerve, zihlolwa ngamathuluzi akhethekile (i-ophthalmoscope kanye nesibani esivulekile).

Ubani ofuna ukumbonisa?

Ngokuvamile, udokotela wamehlo uhlola amehlo futhi anikeze izibuko. Yibo abahlonza la maphutha okukhanya futhi batuse izibuko noma amalensi okuxhumana alungisa lawo maphutha. Kodwa-ke, uma udinga ukubona udokotela wamehlo (isb., i-Glaucoma, i-Cataract, i-Retinal detachment) ukuze uthole ukuhlolwa okujulile, ukwelashwa, noma ukuhlinzwa, kufanele ubone udokotela wamehlo . Udokotela wamehlo angakudlulisela nakudokotela wamehlo uma kudingeka.

Ingabe izibuko noma ama-contact lens angcono?

Manje, uma udokotela ethi udinga izibuko, umbuzo olandelayo uthi, 'Ingabe kufanele ngigqoke izibuko noma `(ama-contact lenses)?' Lesi yisinqumo somuntu siqu ngempela. Kukhona izinzuzo nezingozi kokubili.

Izibuko (Izibuko Zamehlo):

• Izinzuzo:
• Kulula kakhulu ukugqoka nokukhumula. Akukho ukuqeqeshwa okukhethekile okudingekayo.
• Njengoba iso lingathinteki ngqo, ingozi yokutheleleka iphansi kakhulu.
• Ukunakekelwa okuphansi. Azikho "izixazululo" ezikhethekile ezidingekayo, vele usule bese uzigcina zihlanzekile.
• Ungakhetha kusuka ku-`(isitayela)`, `(uhlaka)` oluhlukile, kanye nemibala. Kunezela okuthile okusha ekubukekeni kwakho.
• Kungcono kakhulu kulabo abanamehlo omile kanye nokungezwani komzimba.
• Okubi:
• Kungaba nzima ukwenza imidlalo ethile noma ukuvivinya umzimba, futhi ungase ushelele futhi uwe.
• Ngesikhathi semvula, inkungu ingakheka uma usuka endaweni efudumele uye endaweni ebandayo.
• Abanye abantu bangase bezwe ukucindezeleka ebusweni babo kanye neqhubu kuzo zombili izinhlangothi zekhala labo.
• Umbono ongaphandle ungase uphazanyiswe kancane uhlaka.
• Abanye abantu bangase bazizwe bengakhululekile ngokubukeka kwabo.

Amalensi Okuxhumana:

• Izinzuzo:
• Akubukeki njengesibuko ebusweni, kunikeza ukubukeka kwemvelo.
• Kulula kakhulu kulabo abadlala imidlalo futhi baphila impilo esebenzayo. Akukho sithiyo lapho ugijima noma ugxuma.
• Akukho kuphazamiseka kokubona eceleni. Insimu yokubona isiphelele.
• Kwezinye izimo, njenge-Myopia exakile, kanye nokukhubazeka kwe-cornea njenge-Keratoconus, izibuko zinganikeza umbono ongcono nocacile.
• Akukho nkinga ngemvula noma inkungu.
• Okubi:
• Kudingeka uqaphele kakhulu ngokuhlanzeka. Uma ungawahlanzi kahle amalensi akho, uma ungawakhumuli ngenkathi ulele, futhi uma ungawasebenzisi njengoba kuqondiswe udokotela wakho, ungaba nokutheleleka okukhulu kwamehlo (`(ukutheleleka okukhulu kwamehlo)`) kanye nezilonda ze-cornea. Lena yinto ebaluleke kakhulu!
• Kuthatha isikhathi ukujwayela ukuyifaka nokuyikhumula, kudinga ukuzijwayeza.
• Abantu abanamehlo omile bangase babe nokungakhululeki, ukubomvu, kanye nokulunywa.
• Zingabiza kakhulu kunezingilazi (ngenxa yezindleko zamalensi nesisombululo okudingeka sishintshwe njalo).
• Kumelwe uzisuse ngaphambi kokulala (yize kunezinhlobo ezithile ezikhethekile "zamalensi anwebekayo anwetshiwe", kodwa ngisho nalawo anconywa udokotela kuphela).

Ungazinakekela kanjani izibuko nama-contact lens?

Kubaluleke kakhulu ukunakekela la madivayisi amabili asiza ukugcina umbono wakho ucacile, ngaphandle kwalokho ngeke ukwazi ukuzuza kuwo kahle, futhi `(ama-Contact Lenses)` angalimaza ngisho namehlo akho.

Uma izibuko ziyi:

• Uma ingasetshenziswa, yigcine "ebhokisini" elihlinzekiwe. Ngaleyo ndlela, cishe ngeke iklwebheke noma iphuke.
• Hlanza kuphela ngendwangu ethambile (indwangu ye-microfiber) kanye nesisombululo esikhethekile sokuhlanza ilensi. Ungahlanzi ngekhona lehembe, i-sari, noma i-tissue, njengoba lokhu kungaklwebha amalensi.
• Uma ubeka isibuko etafuleni, ungasibeki amalensi ebheke phansi, ngoba angase aklwebheke.
• Ungahlanzi uhlaka noma amalensi ezingilazi zakho ngensipho noma izinyibilikisi eziqinile.

Amalensi Okuxhumana (khumbula lokhu!)

Ungalokothi uthinte, ufake, noma ususe "ama-Contact Lenses" akho ngaphandle kokugeza izandla zakho kahle ngensipho namanzi bese uzisula ngethawula elihlanzekile! Lona umthetho oyinhloko.

• Hlanza kuphela, ubulale amagciwane, bese ugcina amalensi akho ngesisombululo sokubulala amagciwane esinconywe udokotela wakho noma udokotela wamehlo. Ungalokothi ucwilise, ugeze, noma ufake amalensi akho okuxhumana emanzini ompompi, emanzini asemabhodleleni, ematheni, noma esixazululweni sikasawoti esenziwe ekhaya. Lokhu kungathwala amagciwane angabangela izifo ezinkulu.
• Gcina i-'Contact Lens Case' yakho ihlanzekile ngokususa i-'(isixazululo)' oyisebenzisa nsuku zonke, uyihlanze nge-'(isixazululo) esisha, uyibeke emoyeni bese uyivumela yome. Shintsha i-'(isikhwama)' okungenani kanye njalo ezinyangeni ezintathu.
• Qiniseka ukuthi ususa ama-contact lens akho ngaphambi kokulala, ukugeza, noma ukubhukuda (echibini noma olwandle).
• Ungasebenzisi i-`(ilensi)` efanayo isikhathi esingaphezu kwesikhathi esinqunywe udokotela wakho (isb., i-`(ilensi elahlwayo)` yansuku zonke ingeyelanga, i-`(ilensi)` yanyanga zonke ingeyenyanga). Ungasebenzisi i-`(ilensi)` ephelelwe yisikhathi.
• Uma amehlo akho eba bomvu, eluma, ebuhlungu, efiphele, noma ephuma uketshezi, susa amalensi akho okuxhumana ngokushesha bese ubona udokotela. Ungawaphindi uwafake kuze kube yilapho udokotela wakho ekuyala ukuba wenze kanjalo.
• Ungabelani ngamalensi akho okuxhumana nanoma ubani, futhi ungagqoki amalensi okuxhumana omunye umuntu.

Uma kwenzeka into efana nale, nakanjani bheka udokotela! (Amafulegi Abomvu)

Ngezinye izikhathi izinguquko ezincane emehlweni zingaba uphawu lwenkinga enkulu. Ngakho-ke qaphela kakhulu ngalokho okutshelwayo, ngoba ukwelashwa kusenesikhathi ngezinye izikhathi kungavimbela ukulahlekelwa umbono.

• Uma ngokuzumayo ubona umbono onciphile noma ofiphele (kwelinye iso noma kokubili).
• Uma unesifo esibuhlungu kakhulu emehlweni .
• Uma amehlo akho ezwakala eluhlaza okwesibhakabhaka kakhulu ukuba angabuka ukukhanya noma uma amehlo akho engakwazi ukubekezelela ukukhanya (`(ukuzwela ukukhanya)`).
• Uma amehlo ebomvu, evuvukele, edabukile njalo, noma ephuma ubomvu.
• Uma ngokuzumayo ubona amachashazi amnyama amaningi, ama-web, noma ama-spider web entanta phambi kwamehlo akho, noma uma ubona ukukhanya.
• Uma ubona izinto ezimbili (`(ukubona okuphindwe kabili)`) bese kuqala ngokuzumayo.
• Uma ingxenye yensimu yokubuka ibonakala ilahlekile (njengokungathi ikhethini liwile).

Uma kwenzeka into efana nale , bheka udokotela wamehlo ngokushesha ngaphandle kokulibala noma uzame amakhambi asekhaya.

Ngakho-ke, nazi ezinye izinto okufanele uzikhumbule kulokho esikhulume ngakho (Umyalezo Wokuya Ekhaya):

Ngakho-ke, sikhulume kakhulu ngamehlo, izibuko, kanye `(ama-Contact Lenses)` namuhla, akunjalo? Ukufingqa konke lokhu, nazi izinto ezibaluleke kakhulu okufanele uzikhumbule:

• Amehlo abo bonke abantu ahlukile, ngakho-ke kuyinto evamile ukuthi abanye abantu badinge izibuko, futhi akukho okufanele kube namahloni ngakho.
• Uma ubona ngisho noshintsho oluncane ekuboneni kwakho, qiniseka ukuthi ubona udokotela futhi uhlolwe amehlo akho. Uma isifo sitholakala kusenesikhathi, kulula ukwelapha futhi ungavikela umbono wakho.
• Nquma ukuthi uzogqoka yini izibuko noma ama-contact lens ngokusekelwe endleleni yakho yokuphila, okuthandayo, izidingo zakho, kanye neseluleko sikadokotela wakho.
• Uma ugqoka ama-contact lens, qiniseka ukuthi uqikelela kakhulu ukuwagcina ehlanzekile. Lokhu kubaluleke kakhulu ekuphepheni kwamehlo akho! Ungalokothi ukuthathe kalula.
• Amehlo ayizitho eziyigugu kakhulu futhi ezizwela kalula. Ngakho-ke zinakekele kahle! Izinto ezifana nokudla okufanele, ukulala ngokwanele, kanye nokuthatha ikhefu kuma-computer screen nazo zibalulekile empilweni yamehlo.

Ngithemba ukuthi lolu lwazi luwusizo kuwe. Uma uneminye imibuzo, ungangabazi ukubuza udokotela.

Izibuko zamehlo, Amalensi okuxhumana, Ukukhubazeka kokubona, i-Myopia, i-Hyperopia, i-Astigmatism, i-Presbyopia, ukuhlolwa kwamehlo, impilo yamehlo, amaphutha okubuyisa umbono
